The first two times I heard of Yuntai Mountain was (1) when they opened a newly constructed glass bridge and (2) when they discovered cracks on the glass panels just weeks later. Not a very good first impression, to be honest. If the mountain were a guy in a bar, he would need a better come-on because every interest I had just died right then.
To say that I didn’t know much about Kaifeng would be sugarcoating it. The truth is, I didn’t even know this city has existed until I was already there.
